电厂发电系统谐波危害及其控制探讨

摘要

Harmonic current pollution to the grid in power system is a long-standing problem.In this paper,harmonic control in power generation system is discussed.First,it analyses simply the harmonic currents origin and the dangers,then discusses the restrain measures of harmonic current in the power generation system,and analyses of restrain measures of the commonly used harmonic current,and finally gives a specific harmonic current regulation program.It discusses the regulation programs and application measures from the rectifier and inverter device.%电力系统谐波电流对电网的污染是由来已久的问题,文中对电厂发电系统的谐波治理进行了探讨研究,首先简单分析了谐波电流的产生根源及其危害性,重点探讨了电厂发电系统谐波电流的抑制措施,分析了常用的谐波电流抑制措施,并给出了具体的电网谐波电流整治方案。从整流装置和变频装置两个角度论述了谐波电流的整治方案和应用措施。
